23 represents astand-pipe eirtifiridin fitmthe bottom of'the bowl dewnt hrtu ttig .601- uInn 2. The lower end of ipe 23 islprovided with a Us-shaped section T glass and open to the air at onef'end;

is contained a bodyof 'Inercury as at 24 The pressure of the liquid colur'n l rfoilflonf'ond of the mercury 'naturallycauses theothei: end

of the mercury column to iise more orless.

This mercury column form's" one men'ib erl of a switch which is connectedby a'wire 24f with a'.coil 25, which latter is in "a'state of constant I excitation. A contact-point '26, disposed in the path of the mercury column; forms 'the other member of the switchand alsdfc'dnpre erably of nected with coil 25. Normallyftheseitwo switch members are in contact; but the mo merit the liquid in bowl afallsbel'ow foeftain predetermined level and the pressurefin pi' 28 is consequently insufiicient to hold mercury up to point 26 the contact between the latter and the mercury is broken. The breaking of the circuit at the mercury-switch throws the-full current into a shunt-circuit in which is the electromagnet 27. The latter becoming energized acts upon an armature member 28 on the pump-carriage 16 to draw pulleys 19 and 20 into contact, whereupon the pump is set in motion.

The operation of the pump is only discontinued when the bowl has been replenished above the level suflicient to cause the mercury column to rise again and contact with point 26. The current from the coil will then pass through the low-resistance mercuryswitch and the magnet 27 will release armature 28, allowing the pump to travel away by reason of the spring 29. These intermittent periods of activity of the pump will occur whenever the bowl needs replenishing and once having set the contact 26 (which is adjustable) at the proper point and charged the bowl and reservoir and started the motor the further action of the apparatus is automatic. The bubbles pour out of the bowl in a continuous stream and flow thence down in sinuous form about the supporting-column 2 to the catch-basin formed upon the top of base A. This basin preferably consists of radially-disposed silveredglass sections 30 inclined downwardly toward column 2. The adjacent edges of the sections are slightly separated, and a series of troughs 31 are disposed beneath the spaces between the sections, into which the drip from the bubbles and the condensed liquid is received and conveyed by the spout 32, which is common to all the troughs, back into reservoir 14. The circulation of liquid from the reservoir to the bowl and thence back again is continuous and the operation of the apparatus need only cease when the liquid has become impoverished.

As here shown, the pumpin and blowing and operating mechanism is all housed within thebase, making the ap aratus compact and self-contained and rendering the operation of the device the more mystifying to the casual observer.

The artistic effects may be enhanced by the judicious use of colored electric globes, as shown at 33, and, as seen in Fig. 4, the supporting-brackets for the bowl may be adapted as the respective air-supply, liquid-supply, and gage-pipes 8, 9, and 23.

The bubble -forming fluid may be air, smoke, or any suitable gas. The liquid for use in the bowl while usually a rich soap-suds may be any liquid or viscid substance capable of vesiculation.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

9. In a bubble-fountain, the combination of a liquid-container, a submerged nozzle, a source of air-supply connected with said nozzle, means intermediate the source of supply and nozzle for heating the air, and means for automatically delivering liquid to the container as its contents becomediminished below a certain predetermined point.
